Part E - Use phasors to subtract one sinusoid from another sinusoid Suppose you want to find the difference of two sinusoidal currents, given as follows: ¿1(t) = 1; cos(wt+$1) and iz(t) = 12 cos(wt+$2). If you stay in the time domain, you will have to use trigonometric identities to perform the subtraction. But if you transform to the frequency domain, you can simply subtract the phasors I1 and 12 as complex numbers using y calculator. Make sure that all...
